Lack of faith in humanity (7)
I believe the answer is:
atheism
This clue could be a double definition.
'lack of faith' is the first definition.
(I've seen this in another clue)
'humanity' is the second definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
'in' is the link.
Can you help me to learn more?
(Other definitions for atheism that I've seen before include "Sceptic's position" , "Disbelief in a god" , "displaying opposition to religion" , "A lack of faith" , "Non-belief in God" .)
